I don't know a thing about strings except that which I have read about or listened to at a colloquium or seminar. I don't know if 'branes' transfer ke*2, during their collision. Are there many different sizes of branes, and that is the reason for different types and styles of strings. Are there universal sized branes producing compression of more and more branes of lesser strength yet producing 'strings' within the boundaries of the forming objects. Do they all act the same way, from 'strings' to quarks to/with gluons to baryon. Are strings being formed now at some size in Nature? Would they not be undergoing their 'transformations'? Are baryons being produced in 'free space'? Are there any styles of anything being produced in 'free space'? Which is measurable.......The basic size of the objects that formed the solar system is its' total size. All area, as structure, is pressure density, geometrically/stylistically. contentually (a strange term I made up meaning all of that which is there, as content). temperature, pressure, mass, volume, area. So the question is, can the density be altered to allow its' place in space to express its' density, prevalently.?......since density is energy then any variation of density will be a variation in energy (which is the bond of the force pressure density energy volume and geometry, for the compressed compression pressure density.) which can be and will be one day, used for work.....
